hat I claim as new, and desire to secure by Letters Patent, is-

1. In a massaging implement, the combination of an electric motor, a cam on the motor-shaft and a vibrator engaging with said cam, substantially as described.

2. In a massaging implement, the combination of an electric motor, a cam on the motor-shaft at one end of the motor, and a vibrator having a slotted end embracing said cam, substantially as described.

A massaging implement comprising, in combination, an electric motor, a casing inclosing said motor and adapted to be carried with its contained mechanism in the hand of the operator, a cam on an end of the motor shaft and a vibrator engaged by said cam, substantially as described.

4. In a massaging implement, the combination of an electric motor having a fieldmagnet, an armature journaled at its shaft in said magnet with the shaft projecting beyond the same, a cam on the projecting end of said shaft, and a vibrator engaged by said cam, substantially as described.

5. In a massaging implement, the combination of an electric motor having its fieldmagnet formed of two end spools with a metal bar connection between them and the armature journaled at the opposite ends of its shaft in said spools, a cam on one end of said shaft and a vibrator engaged by said cam, substantially as described.

(5. In a massaging implement, the combination of an electric motor having its fieldmagnet formed of two spools connected by metal bars and the armature journaled at opposite ends of its shaft in said spools, a cam on one end of said shaft and a vibrator pivoted to the adjacent end of the motor and having a slotted end embracing and engaged by said cam, substantially as described.

7. A massaging implement comprising, in combination, an electric motor having its field-magnet formed of two end spools connected by metal bars, the armature journaled at the opposite ends of its shaft in the cores of said spools, and the binding-post on one spool connected by a wire from one terminal with the opposite spool, which is in turn connected by a Wire with the spool carrying said binding-post and with the other terminal of the latter, and a wire connection between each commutator-brush and a terminal on the binding-post, a cam on one end of said shaft, a vibrator engaged by said cam, and a casing inclosing the motor, the whole being adapted to be carried in the hand of the operator, substantially as described.
